glCreateTransformFeedbacks, glTransformFeedbackBufferBase, glTransformFeedbackBufferRange and the three glGetTransformFeedback* queries were all stubs, so a transform feedback object could only be configured and inspected by binding it first - the exact thing direct state access exists to avoid. The queries were the worse half: they returned nothing and raised no error, so an application could not tell that it had learned nothing. glCreateTransformFeedbacks creates the objects outright. glGenTransformFeedbacks only reserves names, and a reserved name becomes an object when it is first bound (GL 4.6 core 13.2.1); the DSA form has no bind step to create them from. The queries and the buffer bindings read and write a named object's state. That state lives in two places: the context keeps one live copy of the capture bindings and the active/paused flags for whichever object is bound, and every other object's copy sits in its saved state until a bind swaps it in. The by-name accessors added to the context resolve that, so a query for the bound object reads the live copy rather than a stale save. GL_TRANSFORM_FEEDBACK_BUFFER_START and _SIZE are answered as zero unless the binding was made by the range form, matching what the buffer object binding points already do. Takes direct_state_access.xfb_* from 0 to 4 of 5 on both backends; xfb_functional still fails on the capture itself, which is a separate defect.
